Answer:
6
Explanation:
Suppose we have a quadratic function f(x) in the following format:
![f(x) = ax^(2) + bx + c, a \\eq 0](https://img.qammunity.org/2021/formulas/mathematics/college/fai1oerr6djx13akhoaag6on8gcfvw96w5.png)
The constant is the value of c.
Also, another way to find the constant is calculating f(0).
In this problem, we have that:
![f(x) = 8x^(2) - 7x + 6](https://img.qammunity.org/2021/formulas/mathematics/college/nbjalin1ibxsmxz22eytz7i59kz09vykmp.png)
So
![a = 8, b = -7, c = 6](https://img.qammunity.org/2021/formulas/mathematics/college/4hel1yclah63kawhpjqukghi9z3zbyv7pf.png)
The constant is c = 6.
Also
![f(0) = 8*(0)^(2) - 7*(0) + 6 = 6](https://img.qammunity.org/2021/formulas/mathematics/college/thm3r9j0tj75rp9fwmrdzozkqdpu8nges9.png)
So the correct answer is:
6
